An unusual mode of energy metabolism discovered in a newly identified microbe provides fresh insights into primitive life processes and offers promising biotechnological applications.

Unearthed in the deep springs of northern California, this organism converts carbon dioxide into energy-rich chemicals using a previously unknown metabolic pathway, potentially mimicking early life mechanisms and paving the way for advancements in microbial manufacturing and biofuel production.

Yikes o.o! What I believe is that we need to have cooling systems underwater to keep things cooler so coral and fish can survive. It could also mean even that fish food supplies could run out in the future from the ocean.

Following a global assessment, the IUCN Red List of Threatened Species has revealed that 44% of reef-building coral species globally are at risk of extinction. The announcement was made at the ongoing COP29 UN climate conference.

Dr. Michael Sweet, Professor of Molecular Ecology and Head of the Aquatic Research Facility at the University of Derby, is among a pool of experts who contributed to the global coral assessment, which has revealed the severe impacts of our rapidly changing climate.

Electrostatic discharge (ESD) protection is a significant concern in the chemical and electronics industries. In electronics, ESD often causes integrated circuit failures due to rapid voltage and current discharges from charged objects, such as human fingers or tools.

With the help of 3D printing techniques, researchers at Lawrence Livermore National Laboratory (LLNL) are “packaging” electronics with printable elastomeric silicone foams to provide both mechanical and electrical protection of sensitive components. Without suitable protection, substantial equipment and component failures may occur, leading to increased costs and potential workplace injuries. The team’s research is featured in ACS Applied Materials & Interfaces.

3D printing is a rapidly growing manufacturing method that enables the production of cellular foams with customizable pore architectures to achieve compressive mechanical properties that can be tailored to minimize permanent deformation by evenly distributing stress throughout the printed architecture.

Breaking oxygen out of a water molecule is a relatively simple process, at least chemically. Even so, it does require components, one of the most important of which is a catalyst. Catalysts enable reactions and are linearly scalable, so if you want more reactions quickly, you need a bigger catalyst. In space exploration, bigger means heavier, which translates into more expensive. So, when humanity is looking for a catalyst to split water into oxygen and hydrogen on Mars, creating one from local Martian materials would be worthwhile. That is precisely what a team from Hefei, China, did by using what they called an “AI Chemist.”

Unfortunately, the name “AIChemist” didn’t stick, though that joke might vary depending on the font you read it in. Whatever its name, the team’s work was some serious science. It specifically applied machine learning algorithms that have become all the rage lately to selecting an effective catalyst for an “oxygen evolution reaction” by utilizing materials native to Mars.

Made from faux Martian and lunar soil, a new sulfur-based compound could also lead to faster construction on Earth.

Pathway has just raised a $10 million Seed round to build live AI systems that, claims the company, think and learn in real-time as humans do.

Viviana Gradinaru, an assistant professor of biology at Caltech, discovered her passion for neuroscience as an undergraduate at Caltech, her alma mater. Viviana did her Ph.D. work with Karl Deisseroth at Stanford University where she played an instrumental role in the early development and applications of optogenetics, a research area concerned with the perturbation of neuronal activity via light-controlled ion channels and pumps. More information on her own lab at Caltech can be found at glab.caltech.edu. Viviana is also interested in entrepreneurship for better human health and has co-founded a company, Circuit Therapeutics, based on optogenetics.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)\ \ .

Bacteria modify their ribosomes when exposed to widely used antibiotics, according to research published in Nature Communications. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance.

Escherichia coli is a common bacterium which is often harmless but can cause serious infections. The researchers exposed E. coli to streptomycin and kasugamycin, two drugs which treat bacterial infections. Streptomycin has been a staple in treating tuberculosis and other infections since the 1940s, while kasugamycin is less known but crucial in agricultural settings to prevent bacterial diseases in crops.

Both antibiotics tamper with bacteria’s ability to make new proteins by specifically targeting their ribosomes. These molecular structures create proteins and are themselves made of proteins and ribosomal RNA. Ribosomal RNA is often modified with chemical tags that can alter the shape and function of the ribosome. Cells use these tags to fine tune protein production.
